How we test

TechRadar aims to produce the most helpful phone reviews on the web, so you're able to make a more informed buying decision.

Part of this testing process includes benchmarking. It's a good way of measuring the overall performance of a product's internal hardware components.

We use Antutu System Benchmark to test tablets. It's a comprehensive Android benchmarking app and produces consistent results.

Antutu measures an Android device's CPU performance, 2D and 3D graphics performance, memory speed and internal and external storage read/write speeds. It combines the results for each test and gives the device a final score.
